one use of 'hovering' sideways is to clear a fence or hedgerow. turn parallel to the fence and hover-taxi sideways over - does two things, limits the time over obstacle in case the donk quits, and you can visually see you have cleared all parts of the ship away from the obstacle before continuing on
what a shame to be halfway over a fence when the donk quits, or think you are clear and settle your tail rotor into it
and yes, of course you would not do this if you are already flying straight and level, more of something that is used in positioning for take-off or back to a ramp or pad
